    Ha! Well ive just run into an issue- my shim/metal base I used on the 135mm isnt the right size for my 50mm... Guess I have to make another trip to ace hardware.

    In the meantime, I got my 35-105 f3.5 macro opened up and added a new aperture linkage- just need those "shims"!

    Finished the 35-105mm f3.5 macro

    Im finding out that longer focal lengths and zooms are MUCH easier to convert- I think I may have to start over on my 50mm aperture linkage- it works but it gets ruff in certain places : (

    At least the 135 and 35-105 rock.

    Hunter I know that wides generally protrude much deeper into the lens mount area, which can cause problems with conversions.

    A typical 135mm lens' rear element, by contrast, is usually way back down the barrel.

    By the time you get to 28mm, it gets very close, and often if not usually a problem for 5D mirrors, but less problematic for 7D etc..

    I even found that with an EOS converted 58mm Minolta, which had such a deep rear element it would "hang" on infinity focus shots on my 5D classic (Mk1), and I'd have to focus a tiny bit down to 10m to get the mirror to return, fortunately without scraping the lens (only the surround).

    For 5D video work, where the mirror's locked up, it may not be an issue at all, if you can physically convert the wides in the first place.

    Just out of curiosity, why not just buy a $20 FD to EOS adaptor and call it a day?

    Those adapters all have 1 of 2 flaws

    1: they don't have a diopter and thus you lose infinity focus

    2: they do have a diopter and you have infinity focus but you have added another glass element (usually a very low quality one) thus lowering the quality of your image.

    +1 There's no substitute for swapping the mount.

    Is it possible with 24mm and 28mm FD's - to convert to EOS? Can it be done?

    If this is the case, you must post a how-to, Hunter! I have a Canon 200mm 1:2.8 FD that I absolutely love (it does surprisingly well on the FD-EOS adapter), but I want to adapt it permanently for the 7D.

    Great work!
